Weiss WT/D Vacuum Test Chamber

Vacuum Temperature and Climatic Test Chambers

Our Vacuum Temperature and Climatic Test Chambers enable reproducible tests of highly stressed components in the aviation industry. The chambers allow the simulation of extreme flight programs in accordance with the relevant standards.

The WK/D and VKH models are available as standard with humidification and dehumidification equipment with a humidity sensor.

Additional chamber options are also available including temperature extension to +180°C, door with observation window and sound insulation.
